Description

The RETALT (Retro Propulsion Assisted Landing Technologies) project aims at investigating launch system reusability technologies for two different Vertical Take-off Vertical Landing launcher configurations, namely RETALT1 and RETALT2. This paper describes and summarizes the CFD based aerothermal load predictions, aerothermal database generation and application for the RETALT1 configuration for the complete trajectory. Furthermore, an analysis of representative CFD results is provided with the aim to show typical flow field phenomena and the resulting heating patterns occurring during the retro- propulsion phase. CFD results are then validated by comparison with the wind tunnel experiments carried out at different ground testing facilities in DLR Cologne.
